Fig. 9 a view similar to Figs. 7 and 8 and .lslhcrvlng the hose couplingsecured tothe llnlthe drawing l have indicated at 1G a part of the hullof a diving bell, one face of which is provided with a plurality ofmagnets 11 usually employed in apparatus of` this classand at 12 1 ,haveindicated the observation Ilenses of apparatus of this class.

- ln the practice of my invention, the hull 10 adjacent to theobservation lenses 12 is provided with an enlarged bearing portion 13through which passes the usual rotary membervor shaft 14 which extendsinto the diving bell and is packed as shown at l5 f and through which,in practice, is passed a rod 16 the inner end of which is packed asshown at 17 and provided with an angular end portion 18, whereby thesame may be rotated by a suitable wrench or crank, and the outer end ofthe rod 16 is threaded as shown at 19. The above named parts may be ofthe usual or any desired construction and the end of the rotary member14 is preferably provided with a conical or tapered aperture 20, theopposite side walls of which are provided with key apertures 21, whichextend the full length of said aperture as shownin Figs. 2 and 5.

Thefenlarged portion 13 of the hull is provided at one side of therotary member 14 with an outwardly directed bearing 22' in which isrotatably mounted a shaft 23,

, the inner end'portion of which is packed as 26 and with an aperture 29in the hull 10 or the enlarged portion 13 thereof. The inner end oftheshaft 23 is made angular in form as shown at 30, whereby a wrench,crank or similar device may bc connected therewith for rotating thesame.

The outer end portion of the shaft 23 pro trudes beyond the bearing 22and secured to the protruding end thereof workpiece carryin member 31,consisting of an approximate y semi-circular disk provided with alurality of threaded ertures 32, 33 an 34 in which are adapte to bemounted respectively a drill 35, a tap 36, and a hose coupling 37 of aump apparatus.

The d 'll 35 is provided) with a central threaded portion 38 rearwardlyof which is an enlarged flange portion 39 havinga reduced and conicalhead 40, the opposite sides of which are provided with ke 41. Thethreaded portion 38 of the rill is adapted to enter the aperture 32 tosupport said drill in the workpiece carryin membeiI 31, and the conicalhead 40 is a apted to enter the conical recess 20 of the rotary member14, and the face of the conical head 40 of the drill is provided with athreaded aperture 42 with which the rod 16, or the threaded end 19thereof operates to retain the drill in connection with the rotarymember,14.

The tap 36 is also provided with a central threaded portion 43rearwardly of which is an enlarged ange 44, having a conical headprovided at theo posite sides thereof with key ribs 46', and t` e faceof the conical head portion is provided with a threaded` Ortion 47. Thewith the workpiece rotary member '14 connection of the 4drill thatsaidtap is connected with the thre aperture 33 in said carrying member.

The hose coupling 37 consists of a main cylindrical body portion 48having a central bore 49 which extends approximately the full length ofthe body portion and forms an externally threaded sleeve 50 at one endof said bod portion, which is adapted to be connecte with the threadedaperture 34 of the workpiece carrying member 31 as shown lin Figs. 1 and2. Inwardly ofthe threaded sleeve portion 50 is an enlarged threadedportion 51 and the other en d portion of the body part 48 of thecoupling is provided with an enlarged flange 52, having a centralconical head portion 53'provid at its opposite sides with key ribs 54,and the face of the conical head connection of the tap 436 carryingmember 31 and will be the same as the therewith, except aded portion 53is provided with a threaded aperture 55 with which the rod 16 of thethreaded end 19 is adapted tobe connected to retain the coupling inconnection with the rotary member 14 as clearly shown in Fig. 2,

is a tool and' A supplemental cylindrical body portion 56' is rotatablymounted on the main body portion 48 of the hose coupling between theenlarged flange 52 thereof and a sleeve 57 secured to the threadedportion 51 as shown in Fig. 5. The supplemental body portion is providedwith an outwardly directed internally, threaded sleeve portion 58fianged as shown at 59 and withwhich is adapted to be connected acouplin sleeve 60 having aiexible tube 61, the ot er end of which isconnected with a suitable pump apparatus on a ship or vessel upon 'thesurface of the water.

The supplemental'body portion 56, or the inner face thereof is providedwith an annular recess 62 forming a port or passage around the main bodyportion 48 of the hose coupling and said main body portion is providedwith a plurality of radial apertures 63 which form a communicationbetween the bore 49 and :the port or passage 62, as clearly illustratedin Fig. 6 of the drawing, and in the operation of the pump apparatus theWater from the sunken vessel or a compartment thereof is pumpedthroughthe bore 49, radial apertures 63 and port or passage 62 outthrough the `internally threaded sleeve portion 58 through the couplingsleeve k6() and thus through the flexible turbe 61.

1n Figs. 7 to 9 inclusive, l. have indicated at 64 a part of the hull ofa sunken vessel and as shown in Fig. 1, and in the operation of my imrovement, the diving bell is rst'lowered into the position adjacent tothe hull in the usual manner and held in contact therewith by themagnets 11, after which the rotary tool holder 31 is rotated from withinthe diving bell by placing a crank on the angular end 30 of the shaft 23to bring the drill 35 on said holder into alinement with the rotarymember 14, and

said drill and workpiece carrying member' 31 is locked in this positionby passin the pin 29 through the proper aperture 2 in the sleeve 26 andinto the aperture 29, after which the rotary member 14 and rod 16 aremanipulated to grasp the conical head 40 of the drill to retain it insaid rotary member, after which said member is rotated to detach thedrill 35 from the workpiece carrying member 31 and to move it rearwardlyout of engagement with saidworkpiece carrying member, after which saidmember is rotated to bring it into the position shown in Fig. 4 topermit the free outward movement of the drill 35 0n the end of therotary member 14 and a hole 6 5 is thus drilled into the hull 64 of thesunken vessel.

After completing the albove operation of drilling the hole 65, thedrillvis moved inwardly to such an extent as to clear the inner face ofthemember 31, after Which said Laeaoei member is rot-ated to bring thethreaded aperture 32 into alinement With said drill and the same isagain connected with the member 31 by reversing the above operation.

The next step is to tap the hole as shown Iat 66 in Fig. 8, whichoperation 1s accomplished by bringing the tap 36 into alinement with therota-ry member 14 by rotating the member 31 and detachxng 1t from saidmember -in the same manner as the detachment of the drill therefrom,andl also in replacing it in the aperture 36 when the hole 65has beentapped.

The next step of the operation 1s the placement or securing of the hosecoupling 37 in the tapped hole 66 of the hull 64, as

shown at 67 in Fig. 9, and'in this operation the pump device is firstbrought into alinement with the rotary member 14, the conical-'headportion 53 thereof connected with the conical aperture 20 of said rotarymember, after which the pump device is detached from the member 31 andmoved into the position shown in Fig. 5, or to clear the inner face ofthe member 31, after which said member is rotated to bring it into theposition shown in Figs. 4 and 5 to permit the hose coupling to passoutwardly of said member, and to be secured to the hull 644 of thevessel as shown in Fig. 9 of the drawing. As hereinbefore statedafterthe hose coupling has been connected with the hull of the sunken'vessel, ora compartment thereof, a signal may be given to the operators.of the ship or vessel controlling the raising and lowering of the divingbell and sui-table pump apparatus put into operation to drawl water fromthe hull or compartment in the hull of the sunken vessel, and after allof such water has bee-ncwithdrawn air may pumped in-to said vessel, oracompartment thereoi1 by utilizing the same hose coupling,

or an independent hose-coupling may `be connected with the samecompartment of the hull in the manner above'described, and as the wateris pum-pedout of such compart-v ment air may be pumped thereintoby asuitable apparatus.

As hereinbefore Stated, the supplemental body portion 56 of the hosecoupling 37 is rotatably mounted on the main vbody portion 48, and thisfacilitates the connection` of the main body portion with the hullwithout rotating the supplemental body portion '56, and saidsupplemental: body portion may thus beheld in an approximately verticalposition 'by the flexible tube 61.

While-1 have shown the workpiece carrying member 31 as capable ofsupporting two tools 'and a single hose coupling, it will be understoodthat my invention is not necessarily limited to the number of tools orcou- 'pling or other attaching devices secured thereto, nor am Inecessarily limited to the spcciic means oi connecting such tools andattaching devices with said supporting member; and various other changesin and modifications of the details of construction herein shown anddescribed may be made, within the scope of the appended claims, withoutdeparting from. the spirit of in v invention or sacrificing itsadvantages.
